Numerical study of the effect of ventilation pattern on coarse, fine, particulate matter removal in partitioned indoor environment.

For that study, a CFD technique has been developed in order to investigate indoor airflow patterns and PM10/PM2.5/PM1 removal ability in ventilated partitioned buildings . A model verification was conducted to compare the full size experiments : A good agreement with the measured mass concentrations is found.
Then numerical simulations of the effect of ventilation on PM removal were performed using three common ventilation patterns (piston displacement, mixing, and cross-flow displacement ventilation). The results and conclusions of the authors are presented.
